FIELD OF THE INVENTION

This invention relates to a gaming machine. More particularly, the invention relates to a gaming machine and to an improvement to a game played on such a gaming machine.

BACKGROUND TO THE INVENTION

Players who regularly play gaming machines quickly tire of particular games and therefore it is necessary for manufacturers of these machines to develop innovative game features which add interest to the games. In so doing, it is hoped to keep players amused and therefore willing to continue playing the game as well as to attract new players.

Also, with the growth that has occurred in the gaming machine market, there is intense competition between manufacturers to supply various existing and new venues. When selecting a supplier of gaming machines, the operator of a venue will often pay close attention to the popularity of various games with their patrons. Therefore, gaming machine manufacturers are keen to devise games which are popular with the players as a mechanism for improving sales, retaining customers and attracting new customers.

SUMMARY OF THE INVENTION

According to the invention, there is provided a gaming machine having a display means and a game control means arranged to control images displayed on the display means, the game control means being arranged to play a game wherein one or more random events are caused to be displayed on the display means and, if a predefined winning event results, the machine awards a prize, the gaming machine being characterized in that the display means includes a plurality of credit meters each of which is allocated to a player of the game for enabling more than one person to play the game and further being characterized in including a credit allocating means such that, when each player deposits credit into the machine, each player's credit is credited to the player's allocated credit meter, the credit allocating means comprising a switch arrangement for allocating that player's credits to that player's meter.

Each credit meter may form part of a set of meters. The set of meters may comprise, in addition to the credit meter, a win meter. Further, the set of meters may include a bet meter. For ease of explanation, each set of meters shall be referred to in this specification as a “meter”.

Each meter may be operable to indicate which player's turn it is and also which player has received a highest win in a round of games played by participating players.

The switch arrangement may comprise a bank of mechanical switches which, conveniently, may be arranged on a midtrim of the machine. The switch arrangement may include a switch associated with each player of the game, the switches being operable to change a turn of each player. Each switch may also be operable to initiate the game for the player whose turn it is.

In addition or, instead of the mechanical switches, the switch arrangement may be implemented by means of touch sensors associated with the display means.

The credit allocating means may be operable, upon completion of play by any one of the players, to pay out each withdrawing player's credit.

In the preferred embodiment of the invention, the machine is intended to be played by at least two players. However, the gaming machine may have a default mode where, if only one player wishes to play the machine, only a single credit meter is displayed and the credit allocating means allocates any credit deposited to said single meter.

The meters may be displayed on the display means alternately depending on which player is playing rather than being displayed simultaneously on the display means.

Further, it will be appreciated that the credit deposited by a player need not be money but could result from a token, an information-carrying card, reference to an account, or the like.

DETAILED DESCRIPTION OF THE DRAWINGS

In FIG. 1, reference numeral 10 generally designates a gaming machine, including a game, in accordance with the invention. The machine 10 includes a console 12 having a video display unit 14 on which a game 16 is played, in use. The game 16 is a spinning reel game which simulates the rotation of a number of spinning reels 18. A midtrim 20 of the machine 10 houses a bank 22 of buttons for enabling a player to play the game 16. The midtrim 20 also houses a credit input mechanism 24 including a coin input chute 24.1 and a bill collector 24.2.

The machine 10 includes a top box 26 on which artwork 28 is carried. The artwork 28 includes paytables, details of bonus awards, etc.

A coin tray 30 is mounted beneath the console 12 for cash payouts from the machine 10.

Referring now to FIG. 2 of the drawings, a control means or control circuit 32 is illustrated. A program which implements the game and user interface is run on a processor 34 of the control circuit 32. The processor 34 forms part of a controller 36 which drives the screen of the video display unit 14 and which receives input signals from sensors 38. The sensors 38 include sensors associated with the bank 22 of buttons and touch sensors mounted in the screen. The controller 36 also receives input pulses from the mechanism 24 indicating that a player has provided sufficient credit to commence playing. The mechanism 24 may, instead of the coin input chute 24.1 or the bill collector 24.2, or in addition thereto, be a credit card reader (not shown) or any other type of validation device.

Finally, the controller 36 drives a payout mechanism 40 which, for example, may be a coin hopper for feeding coins to the coin tray 30 to make a pay out to a player when the player wishes to redeem his or her credit.

Referring now to FIG. 3 of the drawings, a screen display 50 of a game played on the gaming machine 10 is shown. In the embodiment illustrated, the screen display 50 displays two meters 52, 54 in addition to the game display of the game 16. The meter 52 comprises a credit meter 52.1, a win meter 52.2 and a bet meter 52.3. Similarly, the meter 54 comprises a credit meter 54.1, a win meter 54.2 and a bet meter 54.3.

In addition to the bank 22 of buttons on the midtrim 20, the machine 10 includes a credit allocating means comprising a pair of buttons 60 and 62 so that, when each player deposits credit into the machine 10, it is done via the appropriate buttons 60 or 62 as will be described in greater detail below.

The single credit input mechanism 24 is used by both players.

In use, if credit is inserted while the gaming machine 10 is in a state of zero credit without either button 60 or 62 having been pressed immediately beforehand then the gaming machine 10 will function as standard. In other words, there will only be a single meter, meter 52, which is displayed. Otherwise, when the single meter 52 is at zero, two players may commence a combined playing session by first pressing the button 60 after which the two meters 52 and 54 will be displayed. The first player, player A, inserts credit and this is credited to the credit meter 52.1 of the meter 52. If the button 62 is pressed before button 60 has been pressed, a message will be displayed explaining that player A must insert credit first. After player A has finished inserting credit, the button 62 is pressed prior to inserting more credit When button 62 is pressed and the other player, player B, inserts credit, the credit is credited to the credit meter 54.1 of the meter 54. If the credit is not inserted into the gaming machine 10 in a timely manner, for example, within fifteen seconds of button 60 having been pressed while at zero credit, then the screen 50 will revert to a standard display, i.e. with only the single meter 52 being displayed. Similarly, if a game is played only after player A has inserted credit, then the display will revert to the single meter mode with only the meter 52 displayed and any credits won will be credited to the credit meter 52.1 of the meter 52.

Accordingly, when two players wish to play the game 16 on the gaming machine 10, the button 60 is initially pressed when the gaming machine 10 is in a state of zero credit. The meters 52 and 54 default to a current bet and the number of lines applicable to the game result currently displayed.

Thus, as shown in FIG. 5a of the drawings, initially, the credit meters 52.1 and 54.1 both show zero credit. The bet meters 52.3 and 54.3 show the condition as it existed immediately before the start of play by the two players. The win meters 52.2 and 54.2 both initialise to zero irrespective of whether or not the previous single-player game resulted in a win.

Assuming the first player, player A, deposits fifty credits into the machine, the credit meter 52.1 is changed to show the fifty credits as shown in FIG. 5b of the drawings. In addition, the meter 52 is highlighted.

Then, player B presses button 62 and player B inserts twenty credits via the credit input mechanism 24. The meter 54 is highlighted and the twenty credits are credited to the credit meter 54.1 of the meter 54 as shown in FIG. 5c.

Referring now to FIG. 6a of the drawings, if credit is inserted after pressing the button 60 but the button 62 is not pressed or no credit is inserted after pressing button 62, the screen will revert to a display of the single meter 52 and the gaming machine 10 will remain in single player status until the button 62 is pressed. This would cause any bets made using the standard buttons of the bank 22 of buttons automatically to apply to the meter 52. Thus, as shown in FIG. 6a of the drawings, assuming a player inserted forty seven credits into the machine 10 this would be reflected on the credit meter 52.1 of the meter 52 which is also highlighted. However, before player B could press the button 62 and insert any credits, player A commenced playing. Player A bets three credits by pressing the “Bet 1 Credit Per Line” button 58 on the bank 22 of buttons followed by the “Play 3 Lines” button 58. The screen automatically reverts to the single play mode as shown in FIG. 6b of the drawings. Due to a win on payline one, the player is awarded thirty credits which is reflected on the win meter 52.2 of the meter 52.

In FIG. 7a of the drawings, it is assumed that a player is betting two credits per line on two lines. As only a single player had been playing the machine 10, only the meter 52 is displayed.

However, if the button 62 is pressed, and credit is inserted into the machine by player B, the second meter 54 is also displayed as shown in FIG. 7b of the drawings. The meter 54 is highlighted.

It is to be noted that the bet meter 54.3 of the meter 54 defaults to the corresponding bet meter 52.3 of the meter 52.

If, after player B has deposited credit, it is desired that player A plays first, the button 60 is pressed resulting in the meter 52 being highlighted as shown in FIG. 7c of the drawings. Player A then inserts an additional two credits bringing the total credits to seventy credits with this information being displayed on the credit meter 52.1. The meter 52 remains highlighted as shown in FIG. 7d of the drawings.

As shown in FIG. 7e of the drawings player B decides to match the credit of player A and inserts additional credits into the machine. This is effected by pressing the button 62 which highlights the meter 54 and the additional credits, once entered, are reflected on the credit meter 54.1 of the meter 54.

It is then decided that player A should commence playing. The button 60 is pressed resulting in the meter 52 being highlighted as shown in FIG. 7f of the drawings. Player A changes the betting strategy by pressing the “Bet 1 Credit Per Line” button 58 followed by the “Play 3 Lines” button 58, pressing the latter button causing the reels 18 to spin. The result is shown in FIG. 7g of the drawings and, for the win of 5×A on payline three, a win of one hundred and fifty credits results. This win is reflected on the win meter 52.2 of the meter 52.

When the win is made to player A and credited to the meter 52, the win meter 52.2 flashes to indicate that it is the highest current win. Also, after player A has completed playing, the turn automatically transfers to player B and the meter 54 is highlighted.

Player B then, via the button 62 causes the reels 18 to spin. For the 3×A on payline two, a win of thirty two credits is awarded to player B. This is reflected on the win meter 54.2 of the meter 54 as shown in FIG. 7h of the drawings. The win meter 52.2 continues flashing as, to date, it had the highest win.

In FIG. 7i of the drawings, player A decides to increase the bet to two credits per line and does so by pressing the “Bet 2 Credits Per Line” button 58 of the bank 22 of buttons before player A presses button 60. The new bet is reflected on the bet meter 52.3 of the meter 52. After spinning of the reels 18, no win results and the turn transfers to player B as shown by the highlighted credit meter 54 on the screen 50. Also, as a result of player B having the previous win with player A not having won anything on player A's turn, the win meter 54.2 flashes. Player B decides to remain with betting one credit per line and, accordingly, the information displayed on the bet meter 54.3 of the meter 54 remains unchanged. Player B then causes the reels 18 to spin via the button 62. No win results as shown in FIG. 7j of the drawings. Thereafter, the meter 52 is highlighted indicating that it is, again, the turn of player A.

During the two player mode, any credit that is added to the gaming machine 10 will be credited to the meter of the player whose turn is indicated by the highlighted meter 52 or 54. Hence, during a two player session a player must await that player's turn before adding more credit. Also, during two player mode, as soon as one credit meter reaches zero then, when it next becomes that player's turn, a message advising the player to insert more credit will be displayed. If more credit is added, it will go to the meter 52 or 54 of the player whose turn it is and whose credit meter 52.1 or 54.1 is currently reading zero. Alternatively, if the other player button is pressed then the screen will revert to single player mode and the current values of all of the other player's meters will be transferred to the single set of meters which will normally be displayed on the left side of the screen 50. Play will then continue in single player mode requiring bets to be made from the standard bet buttons.

At any time when the gaming machine is in idle mode, the current available credit can be collected from the gaming machine. This is effected by pressing the “Collect” button of the bank 22 of buttons. All credits on both credit meters 52.1 and 54.1 will be paid out by the appropriate method whether it be by hopper, ticket printer, attendant pay, or any other method. It is preferred that the payout procedure results in the credits from the two credit meters 52.1 and 54.1 being dealt with separately in a single payout. Thus, for example, all the credits from credit meter 52.1 are paid out first followed by a pause to enable those credits to be collected and then the credits from the credit meter 54.1 are paid out or vice versa. It will be appreciated that variations of the payout procedure are possible.

In another embodiment of the invention, the buttons 60 and 62 may need to be pressed for changing the player turn. Thus, one of the players could have more than one turn before play is transferred to the other player by pressing the appropriate button 60 or 62. It will be appreciated that, in this embodiment, the button 60, 62 are not used to start the reels 18 spinning. Rather, one of the buttons 58 of the bank 22 of buttons will need to be pressed to start the reels 18 spinning as, otherwise, the gaming machine 10 would not be able to distinguish between a bet being made and a player turn being transferred. Still further, instead of separate bet meters 52.3 and 54.3 of the meters 52 and 54, a common bet meter may be provided. In this way, when in two player mode, the players will be encouraged to bet the same amount as each other. Once the bet has been initialised by one of the players, the same bet will apply in respect of each player's turn until the bet is manually changed by one of the players.

Hence, it is an advantage of the invention, that a gaming machine 10 is provided which promotes sociable gaming by automating the process of two or more people competing against each other on a single gaming machine. Essentially, a “mini tournament” is created. In this way, friends can play the same machine but can still bet from their own separate budgets keeping their own winnings to themselves and without being forced to bet on separate machines in order to do so.

It will be appreciated by persons skilled in the art that numerous variations and/or modifications may be made to the invention as shown in the specific embodiments without departing from the spirit or scope of the invention as broadly described.
